Power Delivery Provider Capabilities

The USB PD Provider capabilities may be selected via the CFG_SEL0 and CFG_SEL1 pins, as defined in Section 3.3,

"Configuration Selection (CFG_SEL0/CFG_SEL1)". Each of the PD Provider capabilities are detailed below. When

capabilities are combined, it is possible that a device can support two or more currents for the same voltage. In this case,

the device will only advertise one voltage with the highest current.

For example, a device that specifies support for “Profile 2 + 5V@3A” must support 5V@2A, 12V@1.5A and 5V@ 3A.

In this case, the device will advertise only two Power Data Objects (PDO): 5V@3A and 12V@1.5A. The device will not

explicitly advertise 5V@2A. However, a consumer that requires 5V@2A will request the 5V@ 3A PDO but only consume

2A.

VSafe5V-L (5V@1A)

The Provider Capability Profile for VSafe5V Legacy (5V@1A) indicates that the UPD1002 supports providing 5 V at 1 A.

This is typically used in dual-role ports that offer no real capability at 5 V (e.g., a Standard-B Consumer-Provider Monitor

UFP that only supports 20 V), but need to abide by the USB Power Delivery Specification requirement that at least one

VSafe5V PDO be offered. Therefore, the capabilities of a legacy USB port (max 900 mA for USB 3.0) are included.

Profile 1

The Provider Capability Profile 1 indicates that the UPD1002 supports providing the voltages and currents needed to

satisfy the USB PD profile 1, as defined by the USB Power Delivery Specification (5V@2A).

Profile 2

The Provider Capability Profile 2 indicates that the UPD1002 supports providing the voltages and currents needed to

satisfy the USB PD profile 2, as defined by the USB Power Delivery Specification (5V@2A and 12V@1.5A).

Profile 3

The Provider Capability Profile 3 indicates that the UPD1002 supports providing the voltages and currents needed to

satisfy the USB PD profile 3, as defined by the USB Power Delivery Specification (5V@2A and 12V@3A).

Profile 4

The Provider Capability Profile 4 indicates that the UPD1002 supports providing the voltages and currents needed to

satisfy the USB PD profile 4, as defined by the USB Power Delivery Specification (5V@2A, 12V@3A, and 20V@3A).

Profile 5

The Provider Capability Profile 5 indicates that the UPD1002 supports providing the voltages and currents needed to

satisfy the USB PD profile 5, as defined by the USB Power Delivery Specification (5V@2A, 12V@5A, and 20V@5A).

12V@1.5A

The Provider Capability 12V@1.5A indicates that the UPD1002 supports providing 12 V at 1.5 A. This option can be

combined with other provider capability options.

12V@3A

The Provider Capability 12V@3A indicates that the UPD1002 supports providing 12 V at 3 A. This option can be com-

bined with other provider capability options.

12V@5A

The Provider Capability 12V@5A indicates that the UPD1002 supports providing 12 V at 5 A. This option can be com-

bined with other provider capability options.

20V@3A

The Provider Capability 20V@3A indicates that the UPD1002 supports providing 20 V at 3 A. This option can be com-

bined with other provider capability options.

20V@5A

The Provider Capability 20V@5A indicates that the UPD1002 supports providing 20 V at 5 A. This option can be com-

bined with other provider capability options.

Peak Power-Capable Setting 0b11 - 200% (PP-200)

The Peak Power-Capable 200% indicates that the UPD1002 supports providing 200% of the current limit for a 1 ms time

duration at 5% duty cycle. This will add the correct 0b11 bits to the PDO.
